The bubble concept could explain one of the strangest mysteries plaguing astrophysics: Why can't we tell how fast the universe is expanding?
From the forces that keep athletes twirling and sliding, to the weird laws governing the world of the very small, to the far-out concepts of time travel and alternate universes, physics covers a lot of interesting territory. Here, Live Science keeps you abreast of all the fascinating physics discoveries.Physics
As the universe cooled in the era after the Big Bang, a supermassive black hole had already formed in the center of a galaxy, forming a giant engine of energy we can still see today.
Something's up with the North Star, a cepheid. Its distance, mass and age should be easy to measure. But new calculations keep disagreeing with one another and failing to make sense.
A new theory suggests that dark matter might not be made of undiscovered, never-before-seen particles. Instead, researchers write, it might be made from a type of "hexaquark" detected in 2014.
Organizers of the American Physical Society's March conference made the decision to cancel due to coronavirus concerns less than two days before the conference was set to begin.
Physicist Freeman Dyson was known for his work on quantum physics and mathematics, as well as his big ideas about the far future.
The bubbling, raucous quantum vacuum distorts the shape of every hydrogen atom in the universe, and it distorts antimatter "antihydrogen" too.
String theory is a purported theory of everything that physicists hope will one day explain … everything.
If a giant object looks like it's going to slam into Earth, humanity has a few options. A new guide could help NASA decide which one is best.
New images reveal that one of the strangest asteroids in the solar system is also the most covered in craters, after billions of years plowing through the asteroid belt like a runaway train.
Life on Earth likely began with the bubble-like membranes that surround our cells. Similar membranes probably wouldn't form on Titan, according to quantum mechanics.
For the first time, astrophysicists have detected a pattern in fast radio bursts, one of the most mysterious phenomena in the universe.
The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein's theory of general relativity, a new study finds.
